Shame Flysafair

Trying to cancel a flight booked for tomorrow morn and have spent most of the day both online and spending hours contacting the call centre trying to cancel, reschedule or let someone know I'm not going to pitch! Finally, at 6pm, was told by a call centre person that I may be able to reschedule and excitingly went for that option! Then told they cannot assist me with options and that I will need to go online to search alternate flights/dates within my price range and will be charged R300 each way for any changes (will also lose the baggage allowance paid for). Whilst searching online for flights that I don't want, yet trying to book and find alternate dates so as not to lose my entire fare already paid, the costs changed right before my eyes each time I refreshed a screen trying to seek dates that may suit. I then hurriedly called at 6.45 with new, not ideal dates and the call centre says closed 7 to 7 and cut me off. Apparently they must have so many people overbooked for a flight that they don't care that I am trying to tell them I won't be there in the morn, and apparently too many people cancelling daily that they don't care that they ***** your funds with no shame. This is an indication of too few local airlines with the arrogance of take it or leave it!
